Abstract : The purpose of the research facility is to probe the volume of space over a ground-located antenna without disturbing the electromagnetic field, specifically to determine radiation phase, polarization, and amplitude contours. Design and construction are presented of a highly rigid, lightweight, oscillating, nonmetallic tower. It is shown that wood is the best material to use. Solutions to the design problems pertaining to the use of wood are offered. The tower is shown to have a maximum deflection of only three inches under its own weight. This value increases by 1/4 inch for each five pounds of payload. Drawings and photographs are included in the Appendix. (Author)
